` 1Y0 a considerable quantity of the lubricant is lost and wasted through a passage of the lubricant into the chamber in which escaped steam condenses, then requiring the draining off of the lost lubricant with the condensa- 15 tion. It is an object of the present inven-` tion to provide a structure whereby the es` caped lubricant may be salvaged and where by its co-mingling with the condensing Y steam will be prevented. n f 2n' Another object of this invention is the provision ina mechanism of `this class of a structure whereby there is provided a collecting chamber for the escaped lubricant and a condensing chamber for the escaped 25V steam, these chambers being` non-communieating with each other'so that the draining of either chamber may be effectively prevented. l n

Another object of the present invention 3o is the provision of va device of this class which will be simple in structure, economical of manufacture, and highly eificient use. l n y @ther objects will appear hereinafter.

35 The invention consists in the combination and arrangement of parts hereinafter described and claimed.

The invention will'be best understood yby a reference to the accompanyino' drawings which form a part of this speci cation and 3 isa view talenon line 3*-3 of Fig. 4 is a central sectional view throughV the deflecting plate used in the invention.

on line 2-2-ofl ln the drawings I have illustrated lthe invention used with an engine having a horizontally disposed cam shaft 9 on whioh'is mounted acam 10. ln the'constr'uction of engines to which the invention is especially adapted, the cylinders may be arranged in units kand it will appear'obvious from the description that the invention is adapted for use on each of the units. This cam shaft 9y rotates in a chamber 1l which is maintained u filled with oil or a suitable lubricant... Ak roller 12 which is mounted on the forks y15 of the head 16, engages the cam 10, this head 16 is secured to the threaded portion 13 of the valve stem 14 and a suitable engagement 5 washer 17 is mounted on the threaded portion 13 for engaging the spring 18.. This y structure is of a well known type and vis merely described for the purposeof identiy fying the structure and use of the invention.

A roller 19 mounted between the forks 20 i of the head 21 is also engaged between. the

`provided'on one face with the outwardly im projecting` peripheral Bange having the groove2formed therein. A spring 23 engages, at one end, a stationarypart ofthe engine head and at the other end the oil de-V flecting platev 24 so as to retain Athe screw 9, head 42 in engagement with` the end of the valve stein 35, thus preventing a rattle or noisy operation when the device is operated. The groove 25 engages the open end of the cylinder 26 which is embraced by the neck 27 andin spaced relation thereto lexcepting. at its lowerA end. which is provided with the peripheral boss 26 which isa snug t in the neck 27. By maintaining Jthe cylinder 26 in spaced relation to the neclr"27.fan` yoilcollecting chamber 28 is vprovided.communicating with the lower end of which is the drain pipe 29. lFixedly mounted on the valve stem L35 is the washer 30 which engages one end of the spring 3l, the other end of which ene5 gages the guide bushing 34, the springl serving to normally maintain the steam control valve '32 in closed position so as to conl trol communication of the chamber 33 with ,i the steam cylinder. This guide lmember 34 100 projects through the packing 36. The interior of the cylinder 26 forms a chamber 37 in which may collect the condensation of such steam as may escape into the chamber 37 from the chamber A drain pipe 39 communicates with the chamber 37.

The detlecting plate is dished out; as at 38, on its upper surface so as to prevent lateral displacement of the spring 23. Radialiy eX- tending channels i0 are formed on the upper surface of the detlecting plate 2li Vto permit the passage of oil which may collect thereon into the chamber 28. The deiiecting plate 2a is securely held against the nut i2 which is threaded on the portion by the head 2l so that seepage of oil 'through the opening formed in the plato 2li prevented.

in operation; when the cam l0 forces the head 2l downwardly to open the valve 32; oil will seep round the head 2l so as to escape from the chamber il and the present invention ati'ords a means for preserving this oil Which lealrs through. ln a multi-cylinder machine; this oil amounts to a considerable quantity every 2a hours so that from a stand-point of economy alone; the invention is quite desirable. By preventing the oil entering to a position Where it may become comingled with the steam or condensate a more eiiicient operating mechanism is provided and more satisfactory results generally obtained in the operation of such a machine.

The construction; it will be noted; entirely separates the oil collecting chamber from the condensate chamber or the chamber into which escaping steam would pass.
